Title: Method and device for producing dry vapour
IPC: F24F3/12
Filed: 1974-03-06
Abstract: 1456916 Vortex separators; Treating air with liquids AIRWICK INDUSTRIES INC 6 March 1974 [6 March 1973] 10117/74 Headings B1R and B2P A dry vapour from a liquid air-treating agent for use in air-conditioning systems is produced by supplying the air-treating agent to an aspirator nozzle 26 which tangentially directs into the upper end of a vortex separator 12 a spray mist of the agent which thereby moves through the separator in a helical path so that particles of the mist of one micron or less remaining adjacent the centre of the separator and are discharged as dry vapour through a conduit 16 in the upper end of the separator whereas larger size particles collect on the wall of the separator and are removed as liquid through an opening 32 in the lower end of the separator. The conduit 16 has a guide portion 22 which directs the dry air-treating vapour in the direction of the flow of air through an air supply duct 18 of an airconditioning system. The liquid passing through the opening 32 collects in a container 34 and is returned through a conduit 36 to the nozzle 26 by aspiration action produced by compressed air supplied to the nozzle via a line 38 by means of a compressor 40 which may be controlled by a timing mechanism 42. Topping up liquid air-treating agent is contained in a reservoir 44 connected to the conduit 36 and is maintained at the same pressure as the separator by means of an interconnecting conduit 50. The timing mechanism 42 may also control the operation of a solenoid valve 48 which may be provided in conduit 36 so that the supply of liquid agent to the nozzle is stopped by closing the valve just before the compressor itself is stopped whereby, after valve 48 is closed, air will still flow through the nozzle to blow out any liquid remaining in it. In another embodiment, Fig. 4 (not shown), a valved T-connection is connected between the container 34 and the conduit 36, the third branch of the "T" being connected through a syphonic flexible hose to a container for the air-treating agent.
